Has anyone else had this problem. It is getting worse. The last gallon of emulsion that I bought just started wearing off the screen after about 20 prints. (first pic) I bought a new gallon thinking that it was a bad batch and now these spreckles start appearing after about 5 or 6 prints. (second pic)
It is only happening with dark colors. I am using Ulano 925 WR emulsion and printing with TW waterbased ink.
One thing I am worried might be causing it is that I clog up any pin holes with a little emulsion after exposure and re expose the screen again.
I am putting two coats on each side and exposing the screen for 8 minutes with a 1000w metal halide. I am sure about my exposure times.
